Impacted Canine in the Lower Jaw

The problem of an impacted canine in the lower jaw is considered one of the most complex and sensitive issues in the field of oral

and dental medicine. Canines play an essential role in dental alignment, occlusion, and the aesthetic appearance of the smile.

When the canine does not appear in its natural position beside the incisors and premolars and remains buried within the bone, multiple diagnostic and therapeutic challenges arise — not to mention the potential long-term damage and complications if the problem is not treated early.

In this article, we explain the characteristics of an impacted canine in the lower jaw, describe the shape of the upper canine, and review how the surgical extraction of a buried canine is performed.

We also highlight the main complications and potential damage associated with this special dental condition.

Shape of the Upper Canine

Before delving into the details of the impacted canine in the lower jaw, it is important to mention the unique shape and function of the upper canine.

The upper canine is characterized by its relatively conical appearance and sharp edges, which enhance its ability to tear food and guide

other teeth during occlusion.

Usually, the upper canine is longer than the adjacent incisors and more prominent, appearing at a clear angle between the front teeth and the premolars.
The appearance of the upper canine gives a distinctive charm to the smile and defines the angles of the mouth during laughter and speech. However, in cases of jaw crowding, excessive protrusion, or a narrow dental arch, the canine may become trapped or impacted as well.

Dentists emphasize that an impacted canine in the lower jaw is usually more complex than one in the upper jaw because it is often related to bone growth variations and the proximity of the lower nerves.

This makes treatment planning more challenging and requires extremely careful and precise diagnosis.

Surgical Extraction of the Buried Canine

Surgical extraction is the main treatment procedure when an impacted canine is found in the lower jaw, especially if it causes pressure on other teeth, threatens the inferior alveolar nerve, or forms cysts around the buried tooth.

The procedure begins with a detailed clinical examination and radiographic imaging, such as panoramic or 3D X-rays, to accurately locate the impacted tooth and assess its relation to nearby nerves and bone structures.

The surgery is usually performed under local or general anesthesia depending on the patient’s age and the extent of the operation. The dentist makes a small incision in the gum above the canine’s location, then carefully removes the bone surrounding the tooth until it becomes visible.

If cysts or infections are present, the area is thoroughly cleaned and all inflamed tissue is removed.

The dentist takes great care to protect the inferior alveolar nerve and checks for any contact or overlap before extracting the tooth completely. After the operation, simple surgical sutures are placed, and the patient is advised to take antibiotics and painkillers and to avoid hard food for several days.

Early detection of an impacted canine in the lower jaw is crucial, as it reduces the operation time, minimizes complications, and helps preserve adjacent teeth without unnecessary damage or loss.

Complications of an Impacted Canine

Every dental specialist recognizes that neglecting to treat an impacted canine in the lower jaw can lead to serious long-term functional, aesthetic, and health-related consequences.

Among the most important complications:

• Pressure on adjacent teeth:
  The buried canine pushes the dental arch out of alignment, causing crowding or tilting of the incisors and premolars, which can lead to spacing issues or improper contact between teeth.
• Formation of cysts or lumps around the buried tooth:
  Dental cysts or benign tumors often develop around an impacted canine due to continued root growth or irritation of surrounding tissues.
• Injury or damage to the inferior nerve of the jaw:
  In advanced cases, the impacted canine may exert pressure on the inferior alveolar nerve, leading to numbness in the lip or chin, reduced gum sensitivity, or chronic pain and tingling.
• Difficulty in occlusion and chewing:
  The absence of the canine changes the force distribution across other teeth, causing gradual imbalance in occlusion and mastication over time.
• Aesthetic problems in the smile:
  Especially when the canine is missing or abnormally positioned, the smile and facial features lose harmony, affecting self-confidence and overall appearance.
• Increased risk of infection:
  When the tooth remains inside the bone or forms a cyst, infection can spread to adjacent teeth or bone, often causing swelling, pain, or unpleasant odor.

For all these reasons, dentists recommend treating the impacted canine in the lower jaw as soon as it is diagnosed and never ignoring early symptoms to preserve long-term oral and jaw health.

 

Diagnosis of an Impacted Canine in the Lower Jaw

Accurate diagnosis plays a crucial role in determining the appropriate treatment plan for an impacted canine in the lower jaw. The dentist begins with a comprehensive clinical examination to assess the alignment of the teeth and identify any unexplained swelling or pain in the canine area.

Digital and panoramic X-rays are essential tools for locating the exact position of the impacted canine and evaluating its relation to the roots of adjacent teeth and the inferior nerve.
In some cases, 3D imaging (CBCT) is used to provide a detailed view of the tooth’s depth and the thickness of surrounding bone, helping the dentist plan the surgery and avoid nerve complications.

Regular annual dental checkups for children are vital for preventing impacted canines and avoiding future complex surgeries. The earlier the diagnosis, the higher the chances of correcting the eruption path with simple orthodontic guidance instead of surgical intervention.

 

Treatment Methods for an Impacted Canine in the Lower Jaw

The treatment of an impacted canine in the lower jaw depends on several factors — the patient’s age, the condition of adjacent teeth, and the presence of pain or pressure symptoms.

In early cases, it may sometimes be possible to use orthodontic treatment to gradually pull the impacted canine into its normal position using special devices designed to guide the tooth’s movement within the dental arch.

When the tooth is completely buried or causes pressure or inflammation, surgical extraction becomes the first-line treatment, as described previously. After surgery, the dentist may evaluate the need for supportive orthodontic treatment to restore proper dental alignment or place a dental implant to improve occlusion and aesthetics.

In rare cases, root canal treatment for adjacent teeth or cyst removal around the impacted canine may be required. Such cases are closely monitored to evaluate nerve or bone healing and ensure long-term stability of results.

Post-Treatment Care After Impacted Canine Surgery

After treating an impacted canine in the lower jaw, dentists recommend following key post-operative instructions to ensure fast recovery and prevent complications:

• Avoid hard foods for at least one week.
• Maintain gentle oral hygiene using an antibacterial mouthwash.
• Take all prescribed medications regularly, especially antibiotics and pain relievers when needed.
• Monitor for swelling, bleeding, or numbness in the lip or chin, and contact your dentist immediately if unusual symptoms appear.
• Attend all follow-up appointments to check wound healing and ensure the stability of adjacent teeth.
• If orthodontic or implant treatment is planned later, follow your dentist’s instructions precisely to achieve the best outcome.

Impacted Canine in the Lower Jaw – Conclusion

The issue of an impacted canine in the lower jaw represents a distinctive therapeutic challenge in modern dentistry.

Proper management requires accurate diagnosis and a comprehensive understanding of the relationship between bone, nerves, and adjacent teeth.

It is essential not to ignore early signs of this condition and to seek specialized dental consultation to maintain the long-term health and functional beauty of the smile.
Always follow medical advice after treatment and keep up with regular dental checkups to ensure full recovery and avoid long-term complications.

How is the impacted canine diagnosed?	Through a detailed clinical examination, digital and panoramic X-rays, and 3D imaging if necessary.
Can the problem recur after surgery?	Usually not, if the tooth and cyst are completely removed, with regular follow-ups and area monitoring.
What is the cost of surgical extraction?	Between 2000 and 7000 SAR/AED, depending on the clinic, surgical extent, and technology used.
